Key Features
- Fixed 1.2 V output with 200 mV typical dropout enables near-rail-to-rail regulation from 2.1 V Li-Ion or 3.3 V system supplies
- 300 mA continuous output current in compact SOT-223-5 package keeps FPGA core, DSP, and MCU I/O rails stable under dynamic loads
- Ultra-low 0.32 V maximum dropout at 300 mA reduces heat dissipation and extends battery life in portable applications
- RoHS-compliant construction with 6 V absolute maximum input provides robust surge protection for USB-powered and automotive 5 V rail designs
Applications
MCP1824T-1202E/DC is designed for point-of-load regulation in portable electronics, FPGA core voltage rails, and battery-powered IoT nodes that require a stable 1.2 V supply from a 3.3 V or Li-Ion source. The low 200 mV dropout preserves usable battery capacity near end-of-discharge, making it well suited for 1S or 2S lithium-cell systems. Its SOT-223 package with exposed tab also suits space-constrained industrial sensor modules that benefit from local decoupling and thermal spreading.

Frequently Asked Questions
How low is the dropout voltage of MCP1824T-1202E/DC and why does it matter for single-cell Li-Ion designs?
MCP1824T-1202E/DC has a typical dropout voltage of 200 mV and a maximum of 320 mV at 300 mA load. For a single-cell Li-Ion battery discharging from 4.2 V down to 2.7 V, the regulator maintains a valid 1.2 V output until the cell reaches approximately 1.52 V above 1.2 V, extending usable battery runtime compared to regulators with 500 mV or higher dropout.
What is the maximum load current MCP1824T-1202E/DC can deliver, and which processor core voltage rails can it power?
MCP1824T-1202E/DC supplies up to 300 mA continuously at 1.2 V, sufficient to power FPGA core voltage rails (many mid-range devices require 100 mA to 250 mA at 1.2 V), low-power microcontrollers, and DDR termination circuits. The SOT-223-5 package with thermal tab helps dissipate up to 1.8 W with adequate PCB copper area, supporting sustained 300 mA operation.
In a USB-powered sensor module, how does the 6 V absolute maximum input rating of MCP1824T-1202E/DC protect the design?
USB 5 V rails can surge to 5.5 V during hot-plug events and higher during cable faults. The MCP1824T-1202E/DC's 6.5 V absolute maximum and 6 V recommended maximum input provide an adequate safety margin above 5.5 V USB VBUS, preventing damage while the 1.2 V fixed output supplies sensitive analog or digital circuits requiring a tightly regulated core supply well below the 5 V bus.
How does the SOT-223-5 package with thermal tab benefit thermal management at full 300 mA load for MCP1824T-1202E/DC?
The exposed thermal tab of the SOT-223-5 package bonds directly to PCB copper, providing a low-resistance thermal path to the board. When regulating from 3.3 V to 1.2 V at 300 mA, the device dissipates 630 mW; with adequate copper pour (typically 1 cm² to 4 cm²), the junction temperature stays well within the rated limit even at 85 °C ambient, ensuring long-term reliability without an external heatsink.
